Genomic/transcriptomic studies to optimize the biocontrol effect of Stenotrophomonas rhizophila

Description

Abstract: The genus Stenotrophomonas is of high medical, ecological and biotechnologicalinterest due to the versatility of the different species. For example, Stenotrophomonas rhizophilais a model for a rhizosphere- and phylloplane- competent, salt-tolerant biocontrol agent. One ofthe most effective strains S. rhizophila DSM 14405T showed biocontrol activity on various crops(e.g. pepper, oilseed rape, cucumber) under salinated conditions in greenhouse and field trials.Strain DSM 14405T does not only show rhizosphere competence and antagonistic activity; it alsoproduces high amounts of osmoprotective substances allowing it to survive under salineconditions. New insights into its mode of action are presented from transcriptomic studies basedon the genome. Furthermore, this information will be used to optimise the fermentation,formulation and efficiency of the biocontrol agent.
